In a news release, the bureau said it has received several calls from consumers and businesses who say they have been called by people claiming to be from ComEd. The callers threaten to shut off their power if they do not receive payment on a delinquent bill.

Paul Callighan, spokesman for ComEd, said in the release that the scammers appear to have tied their calls to the company’s billing cycle, and the company is investigating.

Many of those being targeted are senior citizens, the news release said. The bureau recommends that anyone who receives an unsolicited call from someone claiming to be with ComEd should hang up and call the company’s customer service department at 1-800-EDISON1.

They should also stop payments on any check or credit card given to the phone solicitor, and contact local police if they suspect they have been a victim of fraud.
